Gordon Sigurjónsson had already participated in 1908 in the demonstration sport of glíma. He emigrated to Canada and also fought with the Canadian Expeditionary Force during World War I from 1916-19, including four months with the British Army in Germany. He was the coach of the Winnipeg Falcons when they won the gold in the ice hockey tournament at the 1920 Summer Olympics. Shortly after the tournament he was recruited by the Swedish Athletics Association as a coach for their team at the Games in Antwerp. He later returned to Iceland and became a merchant in Reykjavik. In 1924, when he was superintendent of a mental hospital, he was the last man to be sentenced to prison for homosexual acts in Iceland. Some years later he received a Royal Pardon by the King of Denmark.
